Effects of feeding Aloe Vera Leaves Powder on Performance, Carcass and Immune Traits of Broiler Chickens

Abstract

The current study was carried out to study the effect of dietary supplementation with Aloe Vera leaves powder (AVLP) as natural feed additives on growth performance, carcass characteristics and immune response of broiler chickens. Ross unsexed one day old (75 gm) broiler chicks (n=90) were randomly divided into five experimental groups; each group with three replicates (18 chicks/group; 6 chicks/replicate). Diets supplemented with AVLP at rates of 0, 1.5, 2.0 and 2.5 % and the last group supplemented with antibiotic (Oxytetracyclin 1 g/kg diet) for 42 days. Body weights and feed residues were monitored weekly. At the end of the trial, three birds/group were euthanized and then blood samples were collected, moreover carcass dressing and visceral organs were collected and weighed. Results revealed that AVLP had no significant (P>0.05) effects on growth performance of broiler chicken. All treated groups showed non-significant (P>0.05) effect on internal organ weights and carcass traits. Diets supplemented with 1.5, 2.0 and 2.5 % of AVLP stimulate the immunity by increasing the phagocytic capacity and antibody titre against Newcastle disease virus when compared with the control group. These results indicated that addition of AVLP in broiler chicken's diets has no adverse effects on growth performance beside it improves the humoral and the cellular immunity.

Impact of Dietary Addition of Aloe Vera Leaves Powder on Productive Performance, Caecal Ecosystem and Some Physiological Parameters of Growing Rabbits

“…The full, fresh AV leaves were purchased from a nearby market, cleaned under running tap water, dried in a hot air oven at 50°C and then 105°C until they reached a constant weight, and then ground into fine powder using a manual grinder as described by Mohamed et al (2017). Resulting powder of AV leaves was stored in the dried bottles till use by mixed with commercial pelleted diet in the presence of Blood constituents: Blood samples of growing rabbits were collected immediately after slaughtering in heparinized glass tubes from 3 rabbits / treatment.…”

Influence of Aloe vera (Aloe barbadensis M.) as an alternative to antibiotics on the growth performance, carcass characteristics and haemato‐biochemical indices of broiler chickens

“…However, Mohamed et al. ( 2017 ) reported significant improvement in dress weight and intestinal organs weights of broilers treated with extracts of Aloe vera gel. The disparities could be attributed to the proportion of the Aloe vera extract used and the mode of incorporation.…”

“…This observation supports the results ofShokraneh et al (2016) who found that carcass yield and internal organs weights were not significantly affected by Aloe vera gel extracts supplementation. However,Mohamed et al (2017) reported significant improvement in dress weight and intestinal organs weights of broilers treated with extracts of Aloe vera gel. The disparities could be attributed to the proportion of the Aloe vera extract used and the mode of incorporation.…”

“…This has led to the use of antibiotics that can modify the intestinal microbiota and eliminate harmful bacteria which in turn improves the growth of their birds (Ayoola et al., 2020 ). Antibiotics as growth promoters have been very helpful in improving poultry growth, performance and feed conversion ratio (FCR), but the continued antibiotic treatment of poultry has resulted in residues in poultry products and bacterial resistance against treatment in humans (Mohamed et al., 2017 ). Despite rigorous withdrawal measures to prevent antibiotic residues in food, some drug residues still enter the human food chain and lead to increased antibiotic resistance (Ayoola et al., 2020 ).…”
